If you have Java installed, you can check the version in the Java Preferences utility in your /Applications/Utilities/ folder, or you can launch the Terminal and run the command "java -version" to see an output of the current active version on your system.

Flashback is technically not a trojan-horse application at all, but a "drive-by download" that infects computers by exploiting a vulnerability in Web software.
That makes it much worse than a trojan: You just need to visit a malicious site, without downloading the wrong app or entering an admin password, to have this program silently take command of your Mac and begin altering the content of Web pages.
That also sets Flashback apart from all of the other Mac viruses you might have heard about over the last few years. But it wasn't hard to see something like this happening.
Flashback attacks a known weakness in the Java software Apple has bundled on Macs but often updated slower than other vendors. Apple released a fix last week —"Java for OS X Lion 2012-001" or "Java for Mac OS X 10.6 Update 7" depending on your version of OS X — but it came too late for the estimated 600,000 Macs infected so far.

According to a report Thursday, more than 600,000 Macs could be infected with the nasty Flashback trojan.
We’ve already detailed how to check your Mac to see if you’re infected — but that requires some command line code, and we know that not all users are comfortable doing that.
Now we’ve gone one step further and wrapped those commands into two AppleScripts.

There are reports that some 600K Macs have been infected, perhaps by some estimates 1 percent of the installed base of Macs. As I mentioned in a post last week, Mac OS X Lion and Snow Leopard are running on the majority of Macs. Still, Mac OS X Leopard and Tiger may be running on a quarter of Macs in the world.
Likely, your machines are not infected. Before I installed the Apple updates, I checked my machines using the Terminal checking routine offered by the F-Secure website. It’s the first part of the Manual Removal process.
Yep, I did the same thing. Checked using F-Secure's steps to determine if you are infected. My Mac was clean but if it had not been, they also helped users manually remove it.
Java can be enabled and disabled as needed fairly easily. One can add the Java preferences from Applications/Utilities/Java Preferences.app. Just unclick the two boxes and turn them back on when needed.
Many think that Java is not needed and maybe in some cases that's true for everyday stuff, however, some banks make use of java applets, many remote sessions are powered by java applets as well, and some programs are based on java applets (one such program is RSSOwl and there are many others). Other than banks, there are still some websites that make use of Java applets as well. One that comes to mind is some of the NOAA and JPL, and other astronomy sites that make use of Java applets.
Sure Java can be abused just as Flash, RealPlayer, Quicktime, Windows Media Player/Flip4Mac, javascripting on webpages, and just about everything else that is an Internet facing program. But you don't see everyone trying to uninstall all of those programs...
I would imagine that many people can enable/disable Java as needed just as I noted above for Mac users.
The biggest problem Mac users had to deal with was Apple's two month +/- delay in getting the updated Java update to Mac users so long after Windows and Linux users already had their updates.
